TAP FOR DRAWING OFF LIQUIDS FlROlVl TlNS.

Specification of Letters Patent.

Patented Oct. 1'7, 1905.

Application filed March 30, 1903. Serial No. 150,121.

To all whom it may concern:

Be itknown that I, GEORGE HELLEUR, asubject of His Majesty the King ofGreat Britain and Ireland, residing at Pahiatua, in the ProvincialDistrict of Wellington, in the Colony of New Zealand, have invented newand useful Improvements in and Relating to Taps for Drawing Off Liquidsfrom Tins, of which the following is a specification.

The object of this invention is the provision of a tap which can bereadily attached to a receptacle such as is commonly employed forholding kerosene.

In my invention the screwed stem of the tap is made integral with or hasfixed upon it a cutter which is caused to pierce the sheet metal of thereceptacle and form a hole to receive the stern of the tap which isscrewed into said hole.

In the drawings accompanying this specification, Figure 1 is a sidesectional elevation of a tap, and Fig. 2 a similar View showing the tapattached to a-receptacle.

The tap has a barrel 1, preferably of wood, fitted with a hollow metalplug 2, operable for withdrawal of liquid from a receptacle. In the endof the tap is screwed the tubular metal stem 3, screw-threadedthroughout its length and provided at its end with the projecting end 4.The cutter shown in the drawings is preferably of steel and resemblesthe nose of a boring-bit. The cutter is integral with the projecting end4 and is made by cutting away the part 6 until a sharp point 7 is formedand a cutting edge 8 is formed longitudinally along the sloping rim ofthe central hole 9'. The hole made by the cutter is of the same diameteras the stem at the bottom of the screw-thread, and in operation the stemis screwed into the hole, forming its own thread as it enters.

A washer 5, of cork, is threaded upon the stem and makes a liquid-tightjoint between the tap and the receptacle.

I am aware that faucets have been provided with means for piercing ahole in the can to which the faucet is to be applied and with means formaking a liquid-tight joint. In the patent of James H. Lord, No.105,818, dated July 26, 187 0, such a faucet is described. Therein ahollow auger makes the hole in the can and is then passed completelythrough the Wall of the can into the interior thereof, a

back nut upon the stem of the tap being employed to clamp the wall ofthe receptacle between the vertical back face of the auger and anelastic washer threaded upon the stem of the faucet. In my invention thestem of the tap is parallel, not tapering like an auger, and the cutterintegral with the screwed stem forms a hole in the wall of thereceptacle of diameter equal to that of the stem at the bottom of thescrew-threads thereon. The action of screwing the stem of the tap intothe material of the can clamps the washer against the face of the can,no back nut being required to insure a perfectly fluid-tight joint.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

For the purpose indicated in combination a tap, a tubular metal stemscrew threaded throughout its length adapted to screw into the tap atone end and having a hole throughout its central axis, acutter integralwith the opposite end of the stem comprising a mutilated end terminatingin a point and a cutting edge formed longitudinally along a sloping rimof the central hole, as specified.

In witness whereof I have hereunto set my hand, in the presence of twowitnesses, this 26th day of February, 1903.

GEORGE I-IELLEUR.
